While driving the 40km route to one of the furthest savanna ecosystems in the forestry concession “La Gloria” (Reserva de Biosfera Maya, Petén), we found what we think to be Bignonia binata (also known as bejuco de ajo) flowers. The flowers were emerging from the trunk of the plant, near the ground.
On May 6, at 13:56 pm our team was driving through some of the most well conserved forests in Petén when Sergio, who is part of the team, saw a few purple flowers emerging near the ground. At that moment, he thought that they were terrestrial orchids. Nevertheless, we still had a long route to travel (in order to find more savanna ecosystems that day), and we didn’t stop, so he left a mark in the GPS.

The next day, Teco (our local guide) decided to stop and check the same flowers. He said that he had seen the flowers the previous day, and he wanted to have a better look to check what they could be. That’s when we all noticed that they seem to be “bejuco de ajo” flowers, but they were emerging directly from the trunk, a few centimeters above the ground.
Although we are not still sure about the species, given that there were not any leaves growing at least 10 meters above the ground, we suspect that this plant might be Bignonia binata. This vine is pretty common in Petén and it is difficult not to spot it because it gets huge amounts of bright pink flowers. We have actually found it flowering massively along the roads of Paso Caballos.
What we hadn’t seen before is axilar flowers that emerged from the trunk, a few centimeters above the ground. In this regard, the plant we found was a massive liana that scrambled through the vegetation to reach the tall, perhaps 25m high, canopy. As well, it didn’t have any leaves or flowers that we could spot or photograph with any of the long range lenses that we had at the moment. For that same reason, the two inflorescences that we did get to photograph near the ground not only intrigued us, but also let us identify the species. It would be interesting to do more research on which pollinators inhabit this lower portion of the forest (and for that reason, could pollinate these flowers), and on how this individual plant developed flowers near the ground as a mechanism to attract such pollinators.

Botanical description:Bignonia binata belongs to the BIGNONIACEAE family. It is a vining herb with secondary growth or commonly called "woody". Its opposite compound leaves, with simple tendrils. Its inflorescence is a termile fascicle with 3 white to purple flowers.
It flowers mainly in April, May, June and July and bears fruit in May, July and August. It generally grows on the shores of rivers, lakes and wetlands, entangling itself in trees if it is around it and is distributed from Mexico to Argentina. (Ochoa, Moreno, Jiménez, Ramon, Muñiz & Haas. 2017)

Aristolochia grandiflora is potentially the largest flower of Guatemala. It grows from a relatively thin vine in the Peten and also high in the mountains of Alta Verapaz. Friends provided us the seeds but we had to plant dozens year after year until it decided to grow at 1,500 meters above sea level around the home/office of FLAAR Mesoamerica.
Today there were two of these giant flowers. I show one here; it’s not full size yet, but close.
This side is pink-green; this is the side in the shade, with no sun shining on it.
If you look on the Internet you see photographs of primarily the open part; but in our garden that does not open. And the flower begins to wilt, rot, and falls off it you touch it (to try to turn it so you can photograph it at a good angle; we will show the older flower in an eventual FLAAR Report on this flower. The one here is young; still has a few days to grow before beginning to wilt.
So far one flower has produced a seed pod, about the size and shape of a small cacao pod.
This side is pink-red color; this is the side facing the sun.
In May we continue our exploration in the Reserva de Biósfera Maya (RBM). We had the opportunity to visit the "Multiple Use Zone" where the forestry concessions are located, we focus mainly on “La Gloria” concession. Among the most interesting plant species that we found was the genus Helosis, since at first glance it looks like a fungus. But then we realize it was actually a plant because we have documented it previously in Sayaxche, Petén.
Why does it look like a fungus?
Balanophoraceae is a family of 17 genera of holoparasitic geophytes, that means, a plant that takes all its nutrients from the host plant because it does not have chlorophyll in its tissues. It has roots characterized by an aberrant vegetative and underground body, without leaves, stems or roots, called tuber, which may have rhizome-like branches. These parasitic plants attach to the root of host shrubs and trees of dark tropical forest species. The inflorescences are the only aerial part of the plant and several of them can appear along the rhizomes, making it difficult or impossible to define an individual. A peculiarity of the inflorescences is their endogenous origin (in relation to their own tissues), a unique characteristic in angiosperms. Its flowers are minute and a wide range of extreme reductions can be observed between genera, especially in female flowers and similarly in its seeds, with embryos consisting of few cells (Hansen, 1980; Kuijt, 1969; Mauseth, Hsiao & Montenegro, 1992, Heide, 2008; Su, Hu, Anderson, Der & Nickrent, 2015).
Helosis is one of the genera of the Balanophoraceae family It includes three species, the recently discovered H. antillensis, H. ruficeps and H. cayennensis, that has two varieties: var. cayennensis and var. Mexicana (Gonzalez, Sato & Marazzi, 2019)

Botanical Information:
It has light brown tubers, irregular, with a rough surface, about 20 to 35 mm long by 20-30 mm wide and no more than 20 mm high, located about 5 cm deep. The rhizomes are 4-5 mm in diameter, light brown, branched, aphyllous, arranged parallel to the surface, about 5-7 cm deep. they form a network that begins in the tubers and on them the flower stems are formed. The stems of the underground system are cylindrical, solid, and measure up to 18 cm in height and 1.5 cm in diameter. The base of the peduncle is ring-shaped with bracts 2-5 mm high, welded at their bases and with irregular triangular ends. The inflorescence rises at the end of the floral peduncle, it is an oval spadix that in the adult state reaches about 2.5 to 3 cm wide and up to 5-6 cm long, it is covered by capitate bracts, hexagonal in tangential view, deciduous, 2.5mm wide by 5.5mm high (Fontana & Popoff. 2006).
It is exhausting to hike from base camp (tents far away along Rio Sacluc) to reach Savanna #10. So we have to stop to rest a few minutes every hour (or every kilometer). This seasonally inundated savanna is so large and has so many different ecosystems within its several square kilometers that we visit here several times each year (since in each month different plants are flowering).
Three of the team are resting up in the calabash tree, the other ten are below. A football field behind us are lots of clusters of tasiste palm, found in most seasonally inundated savannas.

Cacao of Guatemala (and surrounding countries of Central America) comes in different species, different surface texture, different colors: each kind of Mayan cacao for great chocolate of different flavors.
Normally this kind of “cacao” is in the western hills of the Maya Highlands. We have also found thousands of this species in groves all around remote areas of Alta Verapaz. We have been driving thousands of kilometers each year to reach remote areas to find and photograph (in high resolution) the different colors and surface texture of different Theobroma species (and different varieties) of cacao. You might enjoy exploring these cacao orchards with us; all are around homes of local people.
I was totally surprised to find this species in the Maya Lowlands (literally near sea level). We thank Cornelio for bringing this to our team last week while we were in this area doing research.
The chemicals from this pod are used to treat other plants to cure them (it releases so many chemicals we have to open the window of the studio and shut the door so the gasses don’t spread throughout the entire office).
This is cacao from a Mayan home garden. The home owner kindly donated the cacao pod so we could bring it back to our photo studio to use lighting to show you the true structure of the surface. Other pods are smooth as silk: we are finding lots of different surface textures. As soon as a donation of funding is kindly sent, we will return to the village with a portable studio and photograph each size, shape, and color up in the tree.
Lots more to come (we have been studying Mayan cacao for over 40 years).
These photographs are in the photo studio at the FLAAR Mesoamerica headquarters, Guatemala City.
We use Westcott studio lighting for illuminating the pods. These are better than any of the Made in China lighting.
We have been studying cacao of the Maya since doing photography for Sophie Coe and Michael Coe’s book on chocolate and cacao many decades ago. I drove all the way to Tabasco to do photographs for this book (in all three editions). I have also photographed cacao in the Soconusco area of Chiapas and throughout Guatemala. We have photographed Theobroma bicolor (pataxte, balamte) in the Maya Highlands of Guatemala.
Yesterday we did a lot of photography of Mayan cacao pods of diverse sizes, shapes, colors, and surface textures. Here is one pod: lots more shapes to come in future FLAAR Reports.
